Class MethodInfo

  wt.loader.MethodInfo

public class MethodInfo

extends Object

This class describes a Method as it is stored in the class file. The attribute associated with method is the code that actually implements the method. Since we don't need to manipulate the byte codes directly we leave them as an opaque chunk in the attributes[] array. References in the code are all references into the constant table so when we are modifing a class to use a different object we needn't get into the code level.
